A new study has found that coral-friendly sunscreen formulas are just as effective in blocking UV radiation as traditional sunscreens. The results of this study offer a promising alternative to traditional sunscreens that contain ingredients that are toxic to coral reefs, and could help protect these fragile ecosystems.

Researchers collected samples of sea water during a two-week period in November 2019. They then tested two different sunscreen formulas on the water samples — one was an organic sunscreen that contained no coral-harming ingredients, and the other was a traditional sunscreen. The results showed that both sunscreens were just as effective as each other in blocking UV radiation.

The findings suggest that it is possible to use sunscreens that are safe for coral reefs, and could help protect these fragile ecosystems. It also raises the possibility of other sunscreen formulas that could be even more effective in blocking UV radiation.
